This paper proposes some consequent-pole modular
permanent magnet machines with different flux gap widths
and slot/pole number combinations. The corresponding inset
modular permanent magnet machines having the same
magnet volume are also presented for comparison. It has been
demonstrated that the output torques of the consequent pole
modular machines are always higher than those of the inset
modular machines regardless of flux gap widths and slot/pole
number combinations. Other electromagnetic performances
such as back-EMF, cogging torque, and iron losses, etc. are
calculated by 2D FEA software and compared as well. The
advantages and disadvantages of consequent and inset
modular permanent magnet machines are summarized in this
paper
